Start in one of the corners next time bro. Starting in the middle is asking for trouble, because the corner - being rounded - has points of relief because of the smaller 90 degree radius, whereas a long straight area when its lifted, stresses along the edge in 180 degrees of direction. And if you use too much pressure, its not only more likely to develop a stress fracture, but then the cracks also have a wide open space to run. (Just take a piece of paper and lay it flat, and see how much of it moves when you lift it at the middle vs the corner.) And when you're putting force on the corner to get a clip to release - you're focused in one small area, as opposed to the middle which again flexes putting more stress on the whole structure, but ironically less than on the one clip you're trying to get to pop. And then you're also concentrating that energy on only one or two clips in a corner, whereas you're working against several along the edge, with each one giving a little and spreading out that energy.. Ultimately, you can get away with anything if you're extremely slow and methodical and go thin edge of the wedge, but why not lessen the surface area potential for cracking while concentrating the force? Should at least extremely minimize the risk, and make the reward that much more NOT a cracking and splintered shards of tech hell that makes you cry while you look through blurry eyes hoping that when the tears blink away it's not as bad as you thought, followed quickly by the confirmation of the horror as you relive the sequence and stomach churning sound that will haunt your dreams for weeks, or however long it takes to replace the shattered remains.I want to report how easy it is to crack the screen on the MediaPad M5 (CMR-W09) while attempting to get to the testpoint. I was using a thin metal cutter to get a foothold, as the plastic guitar picks were not making a dent. I'm now looking forward to using PotatoNV when I get a $14 replacement screen I just ordered from Aliexpress (takes ~2 months to arrive from China to Costa Rica). For the time being, I will continue to use the tablet with a cracked screen and locked bootloader

OP'S tool support only some kirins CPU, not quallcomm ones as on your device.Has anyone had the issue that after connecting the phone with the test-point on, it shows in the Device Manager as QHSUSB_BULK (Qualcomm HS-USB QDLoader 9008) instead of USB_SER (HUAWEI USB COM 1.0), please?
I tried this several times with Huawei Y6 Prime (2018) ATU-L31 (EMUI 18.104.22.168):
1) When the test-point was not shortcut, it showed up in the Device Manager as an Android device after connecting the USB, so normal behavior and battery charging animation started.
2) When I succeeded in shortcutting the test-point, after connecting the USB no battery animation was shown, but it loaded as Qualcomm HS-USB QDLoader 9008 -- and it's not recognized by the Potato NV.
So I suppose I'm doing the test-point procedure right, but why I just can't get it as HUAWEI USB COM 1.0 and be recognized by Potato NV. Any clues, please?
That's correct. Without unlocking the bootloader, you can't alter the way it loads the boot process, which needs to be loaded differently, ie with permissions and other fun things, in order to gain root access, which is in effect THE permission to do whatever the heck you want.hey!
Just so i get this right:
i want to root my tablet to intall magisk.
Do i need to first unlock the bootloader including short wiring the the testpoint and then follow the root procedure specified on page 2?
When i try just rooting without unlocking the bootloader i get ""writing 'recovery'... FAILED" when trying to flash the image.
exact same happened with me . was on LOS16 . Now now matter how many times I short I get the charging screen . Did you find any solution ?It worked for me the first time. But then when I loaded the newest version via Huawei recovery, I lost root and bootloader got locked again.
When I tried the whole process a second time, it didn't work anymore.
Now I get:
on Fastboot & RESCUE MODE
Did anyone find a way to get root back from here?
without code Theres no way to get root ? I also cant get potatoNV to recognize the driver . it directly goes to charging animation
For rooting (installing TWRP or custom ROMs, rebranding), you need to be able to flash. For flashing you need the unlocked Bootloader.
Yes, it is easy.
1 - Turn off the tablet.
2 - Take a conductive wire, copper, alluminum or any other. If you use some wire that is rigid is easier to do it with one hand.
3 - Touch the test point with one end of the wire & the other end touch the electrical ground (Any part of the motherboard, or connector, that is in contact with negative circuit (Ground)).
I used the external part of the usb connector, in my first test I touched the metal shield just together the test point but did not work.
4 - Connect usb cable to computer and tablet, if you need more hands make the computer-tablet usb connection before
5 - Now turn on the tablet, pushing the power button, while keeping the cable connected at both ends.
6 - The tablet will boot with black screen, as if it was off. If you have something on the screen you did it wrongly.
7 - Keep the cable connection for some seconds & you can remove it.
8 - Start PotatoNV.
Thanks!Yes, with this method you can unlock bootloader. After that you can install Magisk following the instructions bellow (at the bottom of the page there are specific instructions for Huawei):
With this you can have a rooted tablet with stock EMUI rom.
Hi Rockel, how did you manage with your T5? Did you fix the issue? How?
I've managed to unlock the bootloader. But still looking for a way to root it.
Thanks for your answer.
I ran PotatoNV under Windows. Don't have much experience with Linux myself. So can't help you with that.
